A pplicati on file'd December 19, 1916. Serial No. 137,754.

To all whom e't may concern."

Be it known that 1, CHARLES O. BURGESS, a citizen of the United States,residing at Monmouth, in the county of Warren and State of Illinois,have invented certain new and useful Improvements in Dilators, of whichthe following is a specification.

My invention consists in a new and useful improvement in dilators,designed more particularly for that type of a speculum, which is to beused with a syringe, for the purpose of dilating a cavity for treatmentwith a liquid to be applied therein by means of the syringe.

My invention resides in the novel combination of an automaticallyadjustable blade of the dilator, for securing the proper dilation, witha shield to secure the proper application and discharge of the liquidsupplied by the syringe, together with the syringe and drainage conduitfor accomplishing same.

The novel feature of the automatic dilation is not limited, however, tothe particular use in connection with a syringe, and I desire to claimthis novel feature for any and all uses for which a dilator may beadapted.

My invention consists in the details of construction hereinafter pointedout.

In the drawings:

Figure 1 is a perspective view of a device constituting my invention.

Fig. 2 is a longitudinal sectional view through the center of Fig. 1

In the drawings:

The numeral 1 designates a dilator provided with a shield 2, to which isrigidly aflixed a blade 3 with which is hingedly connected a blade 4 bymeans of the pivot bearings 5, 5. The blade 3 is fixed at an acute angleto the shield 2. The blades 3 and 4 are provided with longitudinallyslotted portions 3' and 4 respectively. To the inner edge of the blade 4adjacent the pivot bearings 5, 5, there is afiixed the lever 6,

corresponding in form to the adjacent half of the shield 2. This leveris adapted to move the blade 4 in the pivot bearings 5, 5, through anarc of substantially 45 degrees. Opening through the center of theshield 2, from the side which is opposite to the blades 3 and 4, is thedouche 7 in the form of a hollow truncated cone provided with theconical wall 8, to serve as a handle, and

the conduit 9 passing through the center of the douche 7 and providedwith the syringe head 10. At the outer end of the douche 7 there isprovided the drainage conduit 11 provided with a nipple 12 forattachment to a waste pipe.

The operation of this dilator douche will be readily understood from thedescription of its structure. When the blades 3 and 4 are inserted inthe cavity to be dilated the lever 6 bearing against the wallsurrounding the mouth of the cavity will move the blade 4 away from theblade 3, thus distending the dilator and dilating the cavity to anydesired degree until the-lever 6 comes in contact with the shield 2.During this operation the half of the shield 2 adjacent the fixed blade3 and shield lever 6 form a.

complete shield around the opening of the cavity, thus efiectuallysecuring the dilator inoperative position and preventing any leakage ofliquid which is supplied to the cavity by means of the syringe 10 anddischarged therefrom by the discharge conduit 11. The slotted portions3' and 4 permit the liquid to reach the portion ofthe inner surface ofthe cavity covered by the blades 3 and 4. During the operation of thedouche the device may be revolved in the cavity to give thoroughtreatment to all portions thereof. The operation of the lever 6 and theblade 4 make the dilation of the cavity automatic with the insertion ofthe dilator into the cavity, as the degree of pressure, exerted upon thelever 6 by the wall surrounding the mouth of the cavity against whichthe lever 6 contacts in the application of the dilator, determines thedegree of dilation of the cavity.

Having described my invention, what I claim is:

1. The combination of a dilator provided with blades adapted to bedilated automatically when the dilator is applied to a cavity; means forintroducing liquid into the cavity; means for discharging said liquidfrom the cavity; and means adapted to surround the mouth of said cavityto prevent an improper discharge of the liquid from the cavity.

2. A dilator having a plurality of blades adapted to be automaticallydilated by contact with the outer face of the walls surrounding a cavityupon the insertion of the dilator into the cavity; means for introducingliquid into the cavity; means for dis-' charging said liquid from thecavity; and an occlusive shield to prevent improper discharge of theliquid from the cavit i 3. In a vaginal douche, the com ination of ahandle provided, at its center, with a supply pipe and, at one side,with a discharge pipe, an elliptical occlusive shield surrounding saidhandle adapted to contact with the surface of the body surrounding thevagina; and a dilator provided with two coacting blades, one of which isattached to one side of the elliptical shield, the other of which ispivoted to the first and provided with a shield corresponding in shapeto one- 15 half of the shield surrounding the handle.

In testimony whereof I afiix my signature in the presence of twowitnesses.

CHARLES O. BURGESS.
